Standard format events markers
Events are records of non-sample incidents, and can be used to aid interpretation of the deployment data, or for diagnostic purposes.
In Standard format, events and sample data are stored together in chronological order in dataset-1. Sample data should always be stored as complete sets of readings, one set comprising one reading from each active channel, all taken at the same time. However, it may be possible under some fault conditions for only a partial sample set to be stored. It is therefore important when parsing data in Standard format to check for event markers at every reading, not just at the assumed start of every sample set.
Event structure

| Bytes 8 ... 9 | 16-bit count of milliseconds in current second [0 ... 999] |
| Byte 10 | Size of event in uint32_t N |
| Byte 11 | Event processing info |
Bytes 12 ... (4 × N) - 1 | Auxiliary data (for N > 3) |
Seconds for the date/time are counted from 2000-01-01T00:00:00Z.
Event processing info byte
| Bits | Description |
|---|---|
| Bit 0 | 1: the timestamp of this event is the timestamp of the next following sample set 0: the timestamp of this event does not affect the timestamp of the next following sample set |

Auxiliary data
Not all the events have embedded auxiliary data; here is a comprehensive list of those that do, with descriptions of the embedded data.
0x20 Regime bin event auxiliary data
| Bytes | Description |
|---|---|
| Bytes 12 ... 15 | Number of readings in the bin |
There is also a derived data channel, type cnt_00, which contains this value from event 0x20 when in the regimes sampling mode. Refer to the Section "Integrating with a profiling float " for further details.
